3-5. ASSEMBLY INSTRUCTIONS.
a. General. Extreme care must be exercised in all component assembly operations to ensure satisfactory engine
performance. Precautionary rules for assembly are outlined below. Step-by-step procedures for assembly or
various components are covered in the paragraph relating to the specific component.
b. Precautionary Rules.
(1) Cleanliness is essential in all component assembly operations. Dirt and dust, even in minute quantities, are
abrasive. Parts must be cleaned, as specified, and kept clean. Wrap or cover parts and components when
assembly procedures are not immediately completed.
(2) Coat all bearings and contact surfaces with engine oil OE/HDO-10 (MIL-L-2104) to insure lubrication of
parts during initial engine starting.
(3) Replace all gaskets and preformed packings during assembly.
c. Teflon-Wrapped Pipe Plugs. Certain pipe plugs have a thin strip of teflon tape or liquid seal ant applied to the pipe
threads before installation of the plug. This is done to provide a better seal and also to permit easier removal of
the pipe plug. Those pipe plugs requiring teflon wrapping or sealant are identified in the particular assembly
procedure calling for the installation of such plugs. The method of teflon wrapping these particular plugs is as
(1) Be sure that the pipe plug is thoroughly clean and dry before applying teflon tape. All dirt, grease, oil, and
scale must be removed.
(2) Start the tape one or two threads from the small or leading edge of the plug, joining the tape together with
an overlap of approximately 1/8 inch (3.175 mm).
(3) Wrap the tape tightly in the same direction as you would turn a nut. Press the tape into the minor diameter
of threads without cutting or ripping the tape.
DO NOT USE POWER TOOLS; DAMAGE TO EQUIPMENT MAY RESULT.
(4) Torque the pipe plugs to their specified torque. Torque values of engine parts are provided in table 3-3.
